Graph of Parallel lines shows a system of equations with no solutions
Step-by-step explanation:
Consider a set of equations
If we solve this both equations using any one of the solving method, (Substitution method) then we will get
substituting the following x in 2nd equation (21x + 6y = 24) We get
Put y= -2 in x equation
Comparing these (x,y) values we can understand that they never meet at a point
7, 4/11, 7.362, 147/20, 7.99
Yayyy thanks a lottt can i also get brainliest
Answer:
Perimeter=22 m
Step-by-step explanation:
Perimeter Of A Figure
Perimeter is the distance measured around a shape. If the figure is line-shaped, the perimeter can be obtained by adding the individual lengths of each segment around the shape.
The figure shown is surrounded by line segments. We only have to add them all to find the perimeter. But we don't need each individual length to do so. We may notice the following (given all angles are right):
The sum of HG+FE+DC equals AB. So the upper and lower lengths are twice AB, or equivalently: 2*7 1/2 m =15 m
It can also be noted that AH+GF=BC+DE=2 1/4+1 1/4 = 3 1/2 m. It means that the two lateral lengths are twice this value: 2* 3 1/2 = 7 m
Thus, the total perimeter is 15 m + 7 m = 22 m
